7 This invention relates to a device for mixing materials for maxingplastic compositions, and more particularly to a device for mixing anddelivering the material in one operation, and the object is to providedevices which will automatically mix the mait .tobe used and to providea truck the material and horn, which tie mixer may be suspended when itis not desirable to operate the mixer and which truck may be rotated byone Wheel while the other Wheel stands fixed to its axle.

Gther objects and advantages will be fully explained in the followingdescription and: the invention. will be more particularly pointed out inthe claims.

Normally the box 6 or mixer hangs loosely on thearlo 5. locking bar 8 is slidably nonnted on the iront oi the machine ormixer ior temporarily locking the mixer to one oi the Wheels.

Thelocking bar 8 may be further secured in place by a thumb bolt 10 whichscrews through the against the side of the box. The locking bar islocated on the front of the mixer for the cor'ivenience of the operator.The lid 7 is hinged to the mixer at tli'erear upper part andextends-forward. The lid .is locked to the mixer by hasps 11 which arehinged to the lid and engage staples 12 inserted in the front side ofthe mixer. The liasps are pro- The object of these when the truck isbrought the material-is to be used, release the hasps and. pull the lidforward. This will tilt the mixer and dump the material out. The lockingbar 8 must first be released from'the Wheel. If it is not desirable totransportthe mixed material to a different location, one Wheel of thetruck may be locked to the axle by a set screw 14. When the mixer ischarged the truck may berotated, one Wheel rotating without turningWhile the other Wheel revolves. The mixer will thus .be revolved by onewheel While the other Wheel simply rotates Witl10ut turning on the axle.

As an agitating means, bars 15 may be at to the interior of the mixer.These bars will serve to mix or jumble the material as the mixer isrevolved by the Wheel truck.

The'operation issimple. The proper ingredients are lacedin the mixerat-the supply source. ,he mixer is then closed andlocked to one of thetruck WhQElS. By the time the material is transported in the provisionsis that up to place where the operator may bar and presses Wheeled truckto'the place in which it is to he used, the material is thoroughl mixed.The material is discharged from t e mixture as above described.
